Description
Technical field
The utility model relates to a kind of glued board, is specifically related to a kind of composite board for bottom board of container.
Background technology
As everyone knows; Container is big because of its capacity, loading capacity is widely used in the carrier greatly; Simultaneously, caused the problem of container cycle in service life minimizing also because the environment that container itself uses is comparatively complicated, abominable and cargo handling, transhipment frequent.And in the container building block, container wood floor is one of important part.Container wood floor generally adopts the wooden plywood of odd-level; China container industry association is in the JH/TD01 standard of issuing and implementation in 2002; Regulation " timber apron is at least 19 layers of glued board "; One of this essence that requires for the container bottom board odd-level is to realize that glued board is that the material and the rift grain direction of each corresponding veneer of the plane of symmetry is symmetry arrangement with the central core, to reach uniformity and the stability of glued board on mechanical property.
The continuous aggravation in short supply of the present global forest reserves; Particularly high-quality timber resources constantly minimizings such as the higher clone of intensity wood and hardwood; The cost of raw material of container bottom board is also in continuous rising, and the utilization that has had increasing people that sight is transferred to bamboo timber resource in the container bottom board industry comes up.Along with people's is to the continuous exploration and the research of bamboo wood characteristic, and in recent years, the bamboo wood composite more and more receives numerous personages' in the industry concern.
Bamboo wood has vertical tension and the high characteristics of bending strength; Through using the bamboo wood composite; Can be good at increasing the intensity of container bottom board, but, certainly exist bigger slit between the bamboo chip simultaneously because bamboo wood need be processed bamboo chip with bamboo when using is woven into bamboo curtain splint and uses.In the production process of container bottom board; In order to bring into play the high characteristics of bamboo wood bending strength, producer's custom is put in bamboo wood near container bottom board surperficial so that better bring into play the resistance to tension of bamboo curtain splint, guarantees the intensity of container bottom board; But because the radian that slit between bamboo curtain splint and bamboo chip self exist; Cause bad phenomenon such as container bottom board surface irregularity easily, panel is passed through by sand easily when carrying out sanding, and in use panel surface is prone to defectives such as cracking; This not only has a strong impact on the outward appearance of container bottom board, also causes the instability of container bottom board self intensity.Also there is the researcher bamboo curtain splint veneer to be put in the mid portion of container bottom board; Though eliminated the superficial defects that bring in the slit between bamboo chip like this; But fail to get hold of the gummed characteristic of bamboo; Make that the gummed between the bamboo wood is relatively poor relatively, the sandwich layer position is sheared destruction easily, unstable properties in actual production and use.
The utility model content
The utility model purpose: the purpose of the utility model is in order to overcome deficiency of the prior art; A kind of novel structure is provided; Steady quality, production cost is low, overcomes the novel container composite board for bottom board that the bamboo wood characteristic is brought the defective of container bottom board surface irregularity.
Technical scheme: in order to solve the problems of the technologies described above; The described composite board for bottom board of container of the utility model, is formed through precompressed, hot-press gluing through the combination of assembly production line by the multilayer veneer; It comprises upper layer, intermediate layer and following surface layer, and said veneer comprises veneer and bamboo curtain splint veneer; Said upper layer, intermediate layer and following surface layer comprise four layers of veneer and one deck bamboo curtain splint veneer respectively; Layer, intermediate layer are between the two and the intermediate layer, down surface layer is respectively equipped with two-layer bamboo curtain splint veneer and three layers of veneer between the two in the above.
The seeds of said veneer are that clone, A Bidong, Marasse, beech, You Jiali, birch, poplar, Eucalyptus, spoke thank to one or more in pine, larch, the masson pine.
Said upper layer is respectively clone's veneer of the vertical texture of one deck, the mistake bakelite veneer of the vertical texture of one deck, the vertical bamboo curtain splint veneer behind one deck impregnation, the veneer that one deck cross grain is crossed bakelite veneer and the vertical texture of one deck with following surface layer ecto-entad.
Said intermediate layer comprises the horizontal bamboo curtain splint veneer behind one deck impregnation, is located at the bakelite veneer and the vertical veined wood veneer of each one deck excessively of the vertical texture of each one deck of these horizontal bamboo curtain splint veneer both sides.
The glue of in said veneer and bamboo curtain splint veneer, using is synvaren, and solids content is 48 ± 1, in every 1kg glue, adds the 2.4g pesticide.
The moisture content of said veneer≤10%, moisture content≤12% after the said bamboo curtain splint veneer drying, behind the phenolic resin glue dipping, low temperature drying is to moisture content≤18%.
Said bamboo curtain splint veneer is the bamboo curtain splint veneer that braiding forms after removing surf green, tabasheer.
The veneer that said veneer can form required specification through the less veneer mitered of identical texture, toe joint.
The thickness of said container bottom board is 28mm ± 0.5mm.
In the utility model, the built-up sequence of said assembly production line is put surface layer down on streamline; Laterally cross the band veneer of glue, the vertical rift grain bamboo curtain splint veneer behind the impregnation, the horizontal face crossing of crossing glue; Vertical rift grain bamboo curtain splint veneer behind the impregnation, the horizontal band veneer of crossing glue, the intermediate layer that bamboo and wood is compound; Laterally cross the band veneer of glue, the vertical rift grain bamboo curtain splint veneer behind the impregnation, the horizontal band veneer of crossing glue; Vertical rift grain bamboo curtain splint veneer behind the impregnation, the horizontal band veneer of crossing glue, upper layer.
In the utility model, the joining method of the veneer that book size is less is:
(1) veneer is ground to the gradient of width 6-10 degree on the bevel grinding machine, coats phenolic resin glue, two gradients overlap joints behind hot pressing on the bar shaped press, gummed, cut into the veneer of required specification.
(2) veneer is cut into the zigzag that tooth depth is 50mm on the profile of tooth cutter, dock.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: adopt the manufacturing approach of continuous productive process assembly, avoided the phenomenon of the easy entanglement of manual assembly level; Reduced the use of adhesive; Productivity ratio is high, reduced production cost, the blemish when having overcome the bamboo wood characteristic to container bottom board surface irregularity and sanding; Bring into play the anti-bending strength of bamboo wood preferably, guaranteed the quality requirement of container bottom board; Container bottom board through the compound production of bamboo wood utilizes abundant homemade bamboo timber resource, has reduced the raw material supply requirement of the shortage of world forest resources to container bottom board production significantly, has also reduced production cost simultaneously.
